I used to have an 8250 with four RA-81s and a TU-81+.  The power bills
were....impressive. :)


8250 is a VAX, not a PDP-11.  I doubt it even ran off of 120v single phase.
Mine at the University certainly didn't.  I mentioned that RA's were tougher,
but I haven't used one (or owned one) for at least 10 years.  TU-81+?  I
don't remember them being real power hogs, but then I didn't power them
up unless I needed to use them.
